CAR-AXLE BOX.

SPECIFICATION "forming part of Letters Patent No. 400,387, dated March 26, 1889.

Application filed October 22, 1888. Serial No. 288,781. (NomodeL) To all whom it may concern:

Be it known that I, STEPHEN J. AUSTIN, of Terre Haute, in the county of Vigo and State of Indiana, have invented a certain new and useful Improvement in Oar-Axle Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which I Figure I is a sideview of my improved box, showing the axle in section. Fig. 11 is a 1ongitudinal section taken on line II II, Fig. III. Fig. III is a transverse section taken on line III III, Fig. II;

, My invention relates to an improvement in journal-boxes for axles of mining-cars and the like; and my invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents par of the body of a car, 2 the axle, and 3 the journabbox, made in two parts, 4 5, secured together and to the car by means of bolts 6. Upon the axle is cast or otherwise rigidly secured a wide collar, 7, having an annular (preferably V-shaped) groove, 8. This collar is inclosed by the box, as shown in Fig. III, and it turns with the axle within the box. The part a of the box has oil-chambers 9, one on each side of the axle, and the part 5 of the box has an oil-chamber, 10, extending from end to end. V

In the chambers 9 and 10 are necks 11, through which the openings 12, that receive the bolts 6, extend. These necks do not occupy the entire width of the chambers 9 and 10, so that the outer portions of the oilecliambers are not separated from the inner portions, as might appear from Fig. II. Each chamber 9 communicates by means of a port,

13, with the chamber 14:,formed by the annular groove 8 in the collar 7, thus permitting a flow of oil to the collar to lubricate the bearing between it and the box. The chambers 9 are filled through'openings 15, which may be closed by plugs 16. The chamber 10 may re ceive its oil from the waste, or what escapesfrom the chamber 14, through an opening, 17, between wings 18 on the interior of the part 5 of the box; or this chamber may be fed through openings 19, provided with plugs 20.

With my invention the bearing-surface between the collar and the box is kept thor oughly oiled or lubricated without the loss of any portion of the oil.

I claim as my invention 1. The combination of the box provided with oil-chambers, axle, and a grooved collar rigidly secured to the axle and snugly fitted in the box in contact therewith and bearing thereon, said groove forming a chamber co1n= municating with the oil-chambers of the box, substantially as and for the purpose set forth.

2. The combination of a box provided with upper and lower oil-chambers, axle, and a collar rigidly secured to the axle and having a groove forming an annular chamber communicating with the upper and lower chambers,

substantially as and for the purpose set forth.

3. The combination of the box formed in two parts, each part having an oil=chamber, axle, collar'secured to the axle and bearing on said box, and communication between the upper and lower oil-chambers and the bearing-surface between the collar and box, substantially as and for the purpose set forth.

4. The combination of a box having parts 4 and 5, oil-chambers 9 and 10 in the respective parts, ports 13 in the upper part of the box, opening 17 in the lower part of the box, axle, and collar 7 on the axle, substantially as set forth.
